The Difference Between China V and China VI

[MarcusLynn]

China VI emission standards are 40%-50% stricter than China V, making them one of the most stringent emission standards globally. More details about emission standards are as follows: 1. Vehicle Emission Standards: These refer to the regulations on the content of harmful gases emitted from vehicle exhaust, such as carbon monoxide, hydrocarbons, nitrogen oxides, particulate matter, and soot. Many newly launched vehicles now comply with China VI emission standards. 2. China VI emission standards are implemented in two phases: (1) Phase One: Starting from July 1, 2020, all vehicles sold and registered must comply with China VI-A standards. (2) Phase Two: Starting from July 1, 2023, all vehicles sold and registered must comply with China VI-B standards. Some cities will implement China VI emission standards for light-duty vehicles ahead of schedule, starting from January 1, 2019.

I've been driving for over a decade, and the difference between China 5 and China 6 emission standards is quite significant. The China 6 standard is much stricter than China 5, primarily imposing tighter controls on pollutant emissions. For instance, nitrogen oxide emissions are reduced by nearly half, and particulate matter is regulated more strictly. Nowadays, most new vehicles comply with China 6 standards, and you can feel the difference with quieter idling and less air pollution. I remember during the China 5 era, some cars didn't come with particulate filters, but in China 6, especially in phase b, they're almost universally installed. This has made a noticeable improvement in urban air quality. From a user's perspective, China 6 vehicles hold their value better, especially in cities like Beijing, Shanghai, and Guangzhou where traffic restrictions are strict. China 5 used cars struggle with licensing and their prices drop quickly. Choosing a China 6 vehicle when upgrading might cost more upfront, but it saves money in the long run and is more environmentally friendly. With current technological advancements, fuel consumption hasn't increased much, and the government offers subsidies and incentives. I upgraded early and feel it was definitely worth it.
